jQuery EasyUI是一组基于jQuery的UI插件集合，而jQuery EasyUI的目标就是帮助web开发者更轻松的打造出功能丰富并且美观的UI界面。开发者不需要编写复杂的javascript，也不需要对css样式有深入的了解，开发者需要了解的只有一些简单的html标签。
jQuery EasyUI为我们提供了大多数UI控件的使用，如：accordion，combobox，menu，dialog，tabs，tree，validatebox，window等等。
下面通过代码看下easyui datagird编辑行删除行功能，具体代码如下所示：
function init(){ var editRow = undefined; var oldMoney = undefined; $("#dg").datagrid({ url:"../foreignexchange/fexLedgerManager.do?method=queryApplyData&parentId="+parentId, fitColumns:false,//自适应宽度，占满,不能和冻结列同时设置成true striped:true, //斑马线效果 singleSelect:false, //是否单选 pagination:false, height:140, columns:[[ {field:"id", title:"主键", width:'10', align:"center",hidden:true}, {field:"applyNo", title:"申报单号", width:'250', align:"center",editor: { type: 'validatebox', options: { required: true } }}, {field:"exeMoneyString", title:"执行金额", width:'200', align:"center",editor: { type: 'moneybox', options: {precision:2, required: true } }}, {field:"exchangeRate", title:"执行汇率(%)", width:'210', align:"center",editor: { type: 'numberbox', options: {precision:5, required: true } }}, {field:"submitDate", title:"提交日期", width:'190', align:"center",editor: { type: 'datebox', options: { required: true } }}, {field:"executeDate", title:"执行日期", width:'190', align:"center",editor: { type: 'datebox', options: { required: true } }} ]], toolbar: [{ text: '添加', iconCls: 'icon-add', handler: function () { if (editRow != undefined) { $("#dg").datagrid('endEdit', editRow); } if (editRow == undefined) { var submitDate = $("#submitDate").val(); $("#dg").datagrid('insertRow', { index: 0, row: {submitDate:submitDate} }); $("#dg").datagrid('beginEdit', 0); editRow = 0; } } }, /*'-', { text: '撤销', iconCls: 'icon-redo', handler: function () { editRow = undefined; $("#dg").datagrid('rejectChanges'); $("#dg").datagrid('unselectAll'); } },*/ '-', { text: '删除', iconCls: 'icon-remove', handler: function () { var row = $("#dg").datagrid('getSelected'); if(row){ var index = $("#dg").datagrid("getRowIndex",row); $("#dg").datagrid('deleteRow',index); }else{ $("#dg").datagrid('endEdit', 0); $("#dg").datagrid('deleteRow',0); editRow = undefined; } } }, '-', { text: '修改', iconCls: 'icon-edit', handler: function () { var row = $("#dg").datagrid('getSelected'); oldMoney = row.exeMoneyString; if (row !=null) { if (editRow != undefined) { $("#dg").datagrid('endEdit', editRow); } if (editRow == undefined) { var index = $("#dg").datagrid('getRowIndex', row); $("#dg").datagrid('beginEdit', index); editRow = index; $("#dg").datagrid('unselectAll'); } } else { } } }, '-', { text: '保存', iconCls: 'icon-save', handler: function () { var opeRow = editRow; $("#dg").datagrid('endEdit', editRow); var rows = $("#dg").datagrid('getChanges'); if(!rows ||rows.length==0){ alert("无修改数据，无需保存！"); return false; } var allRows = $("#dg").datagrid('getData'); var executeMoney = $("#executeMoney").val(); var sum = 0; var money = 0; $.each(allRows.rows,function(i,row){ row.parentId = parentId; money = formatMeony(row.exeMoneyString); sum+=money; }); if(sum>executeMoney){ alert("执行金额超出台账登记执行金额！"); if(oldMoney){ $("#dg").datagrid('updateRow', { index: opeRow, row: {exeMoneyString:oldMoney} }); } $("#dg").datagrid('beginEdit', opeRow); $("#dg").datagrid('unselectAll'); return false; } //新增 var addRows = $("#dg").datagrid('getChanges','inserted'); //修改 var updateRows = $("#dg").datagrid('getChanges','updated'); //删除 var delRows = $("#dg").datagrid('getChanges','deleted'); var addOrUpdate = $.merge(addRows,updateRows); var addOrUpdateStr = JSON.stringify(addOrUpdate); var delRowsStr = JSON.stringify(delRows); $.ajax({ type:'post', url:'../foreignexchange/fexLedgerManager.do', data : { "method" : $("#method").val(), "addOrUpdateStr" : addOrUpdateStr, "delRowsStr" : delRowsStr }, cache:false, dataType:'json', success:function(data){ if(data.success){ alert(data.msg); init(); }else{ alert(data.msg); } } }); } }], onAfterEdit: function (rowIndex, rowData, changes) { editRow = undefined; }, onDblClickRow:function (rowIndex, rowData) { if (editRow != undefined) { $("#dg").datagrid('endEdit', editRow); } if (editRow == undefined) { $("#dg").datagrid('beginEdit', rowIndex); editRow = rowIndex; var row = $("#dg").datagrid('getSelected'); oldMoney = row.exeMoneyString; } }, onClickRow:function(rowIndex,rowData){ if (editRow != undefined) { $("#dg").datagrid('endEdit', editRow); } } }); } function formatMeony(value){ var money =value; var temp = money.split(","); var result = ""; var value = 0; var size = temp.length; for (var j = 0; j < size; j++) { result = result + temp[j]; } value = parseFloat(result); return value; }
